Polar bears use sea ice as a primary hunting habitat. Climate change is causing major declines in this unique habitat...

Rodents overlap less in their body size distributions in more diverse communities--could this hold a clue to explaining diversity patterns?

Juvenile Microtus pennsylvanicus, North Dakota

By Quentin Read

Ecologists have collected reams of field data, involving much sweat and toil, to explain how competing species — those with similar diets or habitat preferences —...

Forecasting range shifts of a cold-adapted species under climate change: Are genomic and ecological diversity within species crucial for future resilience?

By Spyros Theodoridis

Cold-adapted taxa are experiencing severe range shifts due to climate change and are expected to suffer a significant reduction of their climatically suitable habitats in the next few decades. However, it has been proposed...

How should spatial or phylogenetic eigenvectors be selected? A ten-year review and computer simulation study

By David Bauman

In what context was our study undertaken? Eigenvector mapping techniques are widely used by ecologists and evolutionary biologists to describe and control for spatial and/or phylogenetic patterns in their data....

Plant-bird interactions respond stronger to fragmentation at high than at low elevations

It's a fact. Biodiversity is not uniformly distributed over the Earth's surface. Some regions are lush with a rich...

Dispersal and alternative breeding site fidelity strategies in in the great crested newt

By: Mathieu Denoel

We aimed at examining whether distinct breeding site fidelity strategies may coexist at the intra-population level and how breeding resource characteristics and individual phenotype may affect these strategies in pond-breeding...

Effects of grain size and niche breadth on species distribution modeling

By Thomas Connor

A large body of work in ecology of conservation is devoted to figuring out where species truly are and what causes them to be in some places and not others. Termed species distribution modeling, or SDM for short, this...
